Previously, using Samba 2.2.0 on a Solaris machine, a Windows File browser could receive notification when a file was created in a Samba share. Also, a program using the WIN32 API FindFirstChangeNotification would receive file change notifications from Samba. Now that we have moved to Samba 3.0.10-1.4E.9 on HP/RedHat Linux this no longer works.

What happens now is that the Windows system will initially get file change notifications but if about 1 minute goes by without any new files being created in the share then the notification stops working.
